GtkComboBox implements
AtkImplementorIface, GtkCellEditable
and GtkCellLayout
.
A GtkComboBox
is a widget that allows the user to choose from a
list of valid choices. The GtkComboBox
displays the selected
choice. When activated, the GtkComboBox
displays a popup
which allows the user to make a new choice. The style in which
the selected value is displayed, and the style of the popup is
determined by the current theme. It may be similar to a GtkOptionMenu
,
or similar to a Windows-style combo box.
Unlike its predecessors GtkCombo
and GtkOptionMenu
, the GtkComboBox
uses the model-view pattern; the list of valid choices is specified in the
form of a tree model, and the display of the choices can be adapted to
the data in the model by using cell renderers, as you would in a tree view.
This is possible since GtkComboBox
implements the GtkCellLayout
interface.
The tree model holding the valid choices is not restricted to a flat list,
it can be a real tree, and the popup will reflect the tree structure.
In addition to the model-view API, GtkComboBox
offers a simple API which
is suitable for text-only combo boxes, and hides the complexity of managing
the data in a model. It consists of the functions gtkComboBoxNewText
,
gtkComboBoxAppendText
, gtkComboBoxInsertText
,
gtkComboBoxPrependText
, gtkComboBoxRemoveText
and
gtkComboBoxGetActiveText
.
GtkComboBox
gtkComboBox
is the result of collapsing the constructors of GtkComboBox
(gtkComboBoxNew
, gtkComboBoxNewWithModel
) and accepts a subset of its arguments matching the required arguments of one of its delegate constructors.

Since 2.4
widget
GtkComboBox
] the object which received the signaluser.data
active
[integer : Read / Write]
The item which is currently active. If the model is a non-flat treemodel,
and the active item is not an immediate child of the root of the tree,
this property has the value gtk_tree_path_get_indices (path)[0]
,
where path
is the GtkTreePath
of the active item.
Allowed values: >= -1 Default value: -1 Since 2.4
add-tearoffs
[logical : Read / Write]The add-tearoffs property controls whether generated menus have tearoff menu items.
Note that this only affects menu style combo boxes.
Default value: FALSE Since 2.6
column-span-column
[integer : Read / Write]
If this is set to a non-negative value, it must be the index of a column
of type G_TYPE_INT
in the model.
The values of that column are used to determine how many columns a value in the list will span.
Allowed values: >= -1 Default value: -1 Since 2.4
focus-on-click
[logical : Read / Write]Whether the combo box grabs focus when it is clicked with the mouse. Default value: TRUE
has-frame
[logical : Read / Write]The has-frame property controls whether a frame is drawn around the entry.
Default value: TRUE Since 2.6
model
[GtkTreeModel
: Read / Write]The model from which the combo box takes the values shown in the list.
Since 2.4
row-span-column
[integer : Read / Write]
If this is set to a non-negative value, it must be the index of a column
of type G_TYPE_INT
in the model.
The values of that column are used to determine how many rows a value in the list will span. Therefore, the values in the model column pointed to by this property must be greater than zero and not larger than wrap-width.
Allowed values: >= -1 Default value: -1 Since 2.4
wrap-width
[integer : Read / Write]If wrap-width is set to a positive value, the list will be displayed in multiple columns, the number of columns is determined by wrap-width.
Allowed values: >= 0 Default value: 0 Since 2.4
appears-as-list
[logical : Read]Whether dropdowns should look like lists rather than menus. Default value: FALSE
